3 of them have almost a 4% CTR while the last is straggling behind with a .2% CTR. Google chooses to show this straggling adgroup almost 5 times more often than the successful adgroups. Why is this?
I would think that Google would show the more successful adgroups. Am I missing something?
Better organization is one 'tightly knit theme' per adgroup and then multiple creatives for each group and let adwords do the ad optimization process for you.
